FRANK 0/ A TTORNEK WINDOW CONSTRUCTION AND GUIDE THEREFOR This invention relates to building constructions and more particularly to an improved sliding window construction and a guide therefor. The present application is a continuation-impart of my co-pending application, Serial No. 147,026, filed on March 1, 1950, for Window Construction, which has now become abandoned.

The desirability of providing an inexpensive window guide construction adapted to retain window sections in any position along their range of operative movements has been keenly felt in the art, and numerous constructions directed to the solution of this problem have been devised by those skilled in the art. However, no con struction so far devised have proved to be fully satisfactory.

One of the objects of the present invention is to provide an improved sliding window construction wherein window sections can be easily slid up and down to open and to close the window opening and yet stay in any desired intermediate position of their range of travel without falling or sliding down, particularly when vibrations such as may occur when a heavy vehicle passes nearby or when an adult person walks in the house near the windows, or children run around and play near windows.

Another object of the present invention is to provide an improved sliding window construction which is weatherproof, i. e. sealed from draft, moisture, dust and the like.

A still further object of the invention is to provide an improved sliding window. construction in which the window sections are received between two resilient window guides, the range of permissible deflection and resiliency of which are such that window sections of slightly varying widths, with variations being such as to make the window sections unusable as oversize or undersize in conventional window constructions, can operate successfully in my improved window construction.

A still further object of the present invention is to provide an improved sliding window construction which may be installed in a window opening in an exceedingly simple and easy manner and by an unskilled person and in which the window sections may be subsequently. removed simply and easily for washing, glazing, painting, and the like and reinstalled in an equally easy manner.

A still further object of the present invention is to provide an improved sliding window construction of the friction type in which the window-retaining guides possess suflicient resiliency to provide an operative construction in spite of being made of relatively thin sheet metal stock, and in which the use of additional spring means, such as bronze compression springs and the like, which A may become lost, improperly reinstalled or broken, are

entirely eliminated.

It is an added object of the present invention to provide an improved sliding window construction including a window guide which is exceedingly simple in construction, dependable in operation, easy and simple to install, and inexpensive to manufacture.

Further objects and advantages of this invention will nited States Patent be apparent from the following description and appended claims, reference being had to the accompanying drawings forming a part of this specification, wherein like reference characters designate corresponding parts in the several views.

Fig. l is a fragmentary elevational view showing one side of a window construction embodying the present invention.

Fig. 2 is a sectional view taken in the direction of the arrows on the section plane passing through line 2--2 of Fig. 1.

Fig. 3 is a sectional view of a window guide in its unice deflected condition, i. e. prior to its installation in a window opening.

Fig. 4 illustrates the first step of installing my improved window guides in a window opening.

Fig. 5 shows the second step of such installation.

It is to be understood that the invention is not limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawings, since the invention is capable of other embodiments and of being practiced or carried out in various ways. Also it, is to be understood that the phraseology and terminology employed herein is for the purpose of description and not of limitation.

In accordance with the invention there is provided an improved sliding Window construction in which two window sections slide in two one-piece window guides or channels made of resilient non-corroding sheet material, such as stainless steel, aluminum and the like. Each guide has two window tracks provided therein, and one such guide is provided on each side of the window construction. The guides have such a cross section that, when installed, they are resiliently deflected by the window sections to the degree where they are able to support the window sections in any position thereof along their range of travel solely by virtue of the resiliency of the guides themselves and without the necessity of providing added springs, pins, locks and the like.

At the outer side of the Window opening the guides fit against a permanentlyinstalled retaining board, while from the inner side they are retained in place by removable retaining strips or moldings. Thus, the guides are secured in place without any means that would pierce them, such as nails, screws and the like. When the inner retaining strips are removed, both window sections together with their guides are removed from the window 'opening inwardly of the building, such as for washing,

glazing, etc. and they are reinstalled in a similar manner.

In the drawings there is shown by way of example a sliding window construction for a house of the residential type, embodying the present invention. Referring to the drawings, the window construction illustrated therein has at each of its two sides frame boards or jambs 10 connected at the top by the board 11 and at the bottom by a sill board 12. Permanently installed. retaining strips or moldings 13 are provided within the frame which is formed by the boards 10, 11 and 12, along the outer edges thereof.

Two identical sheet metal guides 15' are provided, which guides extend from the sill board 12 to the top board 11 and fit along the edge of the retaining strips 13. Each of the guides 15 has two parallel tracks formed therein in which slide window sections 20 and 21.

Figs. 4 and 5 illustrate installation of my improved guides in the window opening and assembling the window sections therein. As shown in Fig. 4, the guides 15 which are cut to proper length, are placed with their lower ends on the sill board 12 along the jambs 10, and held apart with the aid of a retainer stick 22. Thereupon, window sections 29 and 21 are slid downwardly into their respective tracks in the guides 15 to approximately the middle of the window opening, as shown. Next,'the guides together with the window sections and 21 are pushed all the way in against the retaining oa ds .3.. and t e inner ret in n st s, 2 ar th ri n p aed" lo s' h i t l i af t s i s's 5 a connected to the'jamb hoards 1Q withthe ne'er screws 24.

i eide are ti le' any Su ta 'n i t dit resilient'sheetiriatlerial such as' sheet aluminum, brass bronze, stainless steel, and the like. Eoi residential house with guides 3 4 wide, sheet aluminum of approximately 1012" thickness gives good results. or th same purpqs tai le et l 9 90 995" may 'us d The u de' re in' d t reb y y 9 rolling to ensure uniforrnity oftheircross section safe as menufes u i s 9 st- .Vhe win s palurnin t ese-sense half-hard. stock is preferred, since it becomes hard due't'o cold wor in rolling. G ner lly. the h c ues nd the d m, .s h i t eleine ts of the cross sec'on of the guides'are so selected and experimentally checkedfthat when the windowhs ss mb d i t gu d s. sa i es re d fl t t a degree where the resilient resistance of the guides alone Becomes suflicient to support the'window section of a predetermined height. Increasing the thickness of the stock increases the weight-supporting capacity of the guides, but at the same time it makes sliding of the window sections moredifiicult. The same is true for decreasing the dimensions of the cross sectional elements of the guide for the same thickness of the stock and deflcbtion. i

In the embodiment illustrated, the window guides in the non-deflected condition have a cross section approxiniately 3" wide and A high. The base of the strip is of arcuate shape, the curvature being such that the theoretical high" point at the center "thereof extends approximately A2 aboye the extremities of the are. When the guide is resiliently defiect'ed'as shown in Fig. 2, its total height is reduced to approximately A" but its width increases to approximately 3% The cr'ds s'sectionis of arrarcuate nature and is so designed that when the guide is installed in place and deflected as shown'in Pig. 2 the guide gently grips the window sections at a large number of places, which appearas points in Fig. 2 but actually extend as lines in an elevationalview. v

Referringspecificallyto Fig. 3, the guide comprises an arcuate base'Zit), the extremities of the cross'section whereof are bent to form inverted channels 31 ekt'ending along" both'side's of the guide. Along the center of the guide there is 'formed .anarcnate head 32. Interbeads 33 are formed.

It can now be seen from an examination of the drawings that when the guide of Fig. '3 is deflected as shown in Fig. 2, a large number ofresilient contact lines are made'by the sides 2).? of the window sections and the guide, as well as'the retaining strips 13 and 23. While mcdiate ly of the head'SZ the channels 31, arrowimproves as time goes on, since sliding of the window sections polishes both the wood and the metal contact surfaces decreasing the friction and improving the seal. Therefore, it is preferred to have the window sections move somewhat tighter when first installed, than it is ultimately desired to have them, since they will work themselves into easier sliding.

It will now be understood'that since the amount of possible deflection in the guides is approximately in each guide, or 1" in both of them, window sections which may vary in their width as much as A", and even more, are received in the guides with substantially the same sealing etfect as those of a precise size, since the guides accommodate themselves to the variations in the window sections widths. It can be easily appreciated that this feature of my guides is of a great practical importance since it permits use of window sections produced with relatively wide manufacturing variations or tolerances. Moreover, swelling ofthe wood of the windowsection'frarhe'due to rrioishire, as well as their shrinkage 'in hot weather do not effect substantially sealing of the window.

My improved window guides may be rolled from rolls of strips of sheet material and distributed to the tradein any desired length such as standard length, or be precut to precisewindow dimensions.

There is thus provided an improved window construction whereby the objects ofthe invention listed above and numerous additional advantagesare attained.
